Need help finding ideal prefab ported box

[GlocksRock 10+ year member]

First off let me say that I know prefab boxes aren't the best option, but that is what I'm looking for right now.

I am looking for a ported box for my 2 eD 13Ov2 subs. the mfg. recommends 1.5per chamber tuned to 30 hz. for sq, and for loudness 1.5 tuned to 35 hz. I was able to find some of boxes with adequate enclosure volume, but most places don't list the tuning frequency of the box. Is there any way to find out what the tuning freq. is by the box size, or would you need to know all the specifics of the enclosure? The closest thing I could find so far is a q-logic box that is 3.0 cubic feet tuned to 37 hz. I also can't have a box that is any taller than 15.5 inches, width and depth aren't too much of a concern, but for a box that is a total of 3.0 cubic feet, or slightly larger the other two dimensions should be ok regardless. I would have a custom box made, but I can't afford it as the local shops charge and arm and a leg, and I don't know of anyone locally that can do it for me.

I see some boxes on ebay list the port lenght, but I don't know if I can figure the tuning frequency by the specs that are listed... is there any way to figure that out?

Is there anyone that actually can help me with the original question? I've never used ported boxes before, so I don't know what I should expect if I use a larger than recommended box with whatever tuning... how does box size and tuning affect the sound?

Unless someone here want's to build me a box and ship it to me for a reasonable price, I don't forsee myself not using a prefab box... or I can just stay using my sealed boxes.

You haved to look around, first what does your subs recommend?

It's in the first post... 1.5 ft.^3 @ 30hz. or 1.5 ft.^3 @ 35 hz. for a louder box.

I know some people have used larger boxes with different tuning, but I don't know how different box sizes affect the sound. I know that a higher tuning will get louder, but at the sacrafice of sq. I want something that gets pretty loud, but still has decent sq, so I was hoping to get something tuned to about 32 or 33 hz.

my bad didnt read the whole post, but anway trying to find a prefab box like that is harder than imaging your parents have ***, I say get someone to build you one. Try local, their usually half the price as the people who advertise on the internet. Its just trying to find someone with good build quality.

I was thinking of just going with this box...

http://www.crutchfield.com/App/Product/Item/Main.aspx?g=178650&i=04412D150S&tp=127

it's the right size, and tuned to 37 hz. so it's not too far off of what eD recommends. I can get it a bit less from somewhere else, and I figure that will be less expensive that paying someone locally to build me a box.

For shits and giggles a couple months back I had a MTX 9500 12" sitting and a pro-box sitting around at 2 cubes tuned to 36Hz..

With 2 SAZ 1500D's @ 1 ohm it did a 147.3 peaking at 45Hz. I'll post up pics of score when I get on my other computer later...//content.invisioncic.com/y282845/emoticons/handclap.gif.0c301076f534e244f0460706894f19e0.gif

how would a box at 1.5 cubes tuned to 35 hz. sound comparted to a 2.0 cubed box at the same tuning? What effect does the volume have on the sound since the tuning is the same?

You want a box tuned to those specs but you want to find it in a prefab? Good luck.

I'm saying, if I can't find one tuned to that, what prefab box would get me closest to that, or would a box that is a bit larger than 1.5 cubes still sound good?
